HORSESHOE-CALK.

Specification of Letters Patent.

Application filed February 1, 1910.

Serial No. 541,262.

To all whom it may concern:

Be it known that I, James I. VAN ron, a citizen of the United States, and a resident of Hudson. in the county of Columbia and State of New York, have invented a new and Improved Horseshoe-Calk, of which the following is a full, clear, and exact description.

The invention is an improvement in horseshoe callcs and resides primarily in the mode of applying the calk to the shoe. this 1 being effected in a way to cause the natural pull on the call: by the horse, tending to separate the call: from the shoe. to fence the section of the same on the line of Fig. 1; Fig. 3 is a section on the line 23-43 of Fig. 1; Flg. l 15 a section on the line -l--et of Fig.

1; and Fig. 5 is a section on the line fir- 5 of Fig. 1.

For the purpose of illustrating the nature of my improvements, I have shown a horseshoe 5 having the toe call: 6 and heel calhs 7, the general form of the shoe and call: being of the customary or other preferred character. The toe call: is provided on its upper side with a number of dove-tailed undercut grooves 8, two being shown, extending parallel to the longitudinal center of the shoe, each groove extending through the forward edge of the call; and inclining downwardly and rearwardly relatively to the upper face of the calk, whereby the sides of the groove are of wedge construction. For each of these grooves the shoe is provided with a screw or other projection 9, which extends to the under side of the shoe, with the head of a size and shape to fit the groove, the head of the screw or other projection being arranged at such a distance from the under side of the shoe, as to cause the call: to bind against this face of the shoe when it is forced to place, as illustrated in forced to the under side or tread of the shoe. thus causing the call: not only to wedge in place but affording a substantial bearing surface and a firm support. The projections of the shoe which are received in the grooves are in the nature of screws, as shown, and it is an easy matter to adjust them so as to cause the binding action of the call: against the shoe to take place at the re quired point. By reason of the arrangement of the grooves, the heads of the screws or other projections are inclosed and protected from injury.

Ordinarily the strain on a horseshoe calk is entirely in a direction to pull the calla forwardly from the shoe. However, there is some danger of the call: working loose and being lost from the shoe by sliding off in the opposite direction. This may be prevented by any suitable means. I, however,

' prefer to employ for this purpose a screw or other projection 10, which is threaded or otherwise removably secured in the shoe and is received 111 a slot 11 extending in the calk from its rear edge, the slot 11 being arranged, in the case of the toe callc, centrally between the grooves 8, the screw or other device 10 passing into the shoe after the calk is applied, and removed before the call: can be knocked from the shoe. The heel calks 7 are applied to the shoe in substantially the same way; only one groove 8, or screw or other projection 9, corresponding respectively to the groove 8 and screw 9 of the toe calk, being provided, and this groove arranged centrally of the calk. The heel call; is shown to be prevented from sliding from the shoe rearwardly by a screw 10. passing through a slot 11 in the heel end of the calk, the retaining device 10 and slot being arranged similarly and corresponding to the retaining device 10 and slot 11 of the toe calk.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

The combination with a horse-shoe, of a call: for said horseshoe having an undercut groove entering at the forward edge thereof ground, due to the natural rearward thrust of said shoe.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES P. VAN NYCK.

and an opening at the top extending downwardly and rearwardly at an inclination to the upper surface of the calk, and a screw detachably connected to said shoe, with its head projecting from the lower surface thereof in such a position as to radially engage said groove in said calk and adapted to co-act with the undercut side of said groove to bind said calk to said shoe when said call: is moved in contact with the l/Vitnesses WV.
